一种用于多相DC-DC降压变换器的简单无传感器均流技术

Multiphase buck converters are widely used to power up low-voltage high-current loads, such as microprocessors, battery chargers, hybrid vehicles, among others. For this converter, topology is necessary to guarantee a correct distribution of the total output current among phases in order to ensure proportionality in electrical losses and thermal stresses. So, a current sharing scheme is a desirabl...
